Group company Hidaka Toshi Gas Co., Ltd. offers management services for vacant houses in which they provide regular inspections and manage the rapidly growing number of vacant houses on behalf of the owners as more and more of them are inherited from the baby-boom generation due to the declining birthrate and aging of society.
A municipal ordinance in Hidaka City states that "vacant houses are to be properly managed and maintained." We aim to continue enhancing these services as a business that is useful for solving problems faced by local communities.
